• 95.95% silver purity achieved in 5 minutes
• Comparable to Britannia-grade silver, a premium alloy
• Significantly higher purity than conventional recovery methods

Lithium Universe Limited (ASX: LU7) is pleased to report further highly encouraging results from its ongoing research into advanced silver recovery techniques. Recent trials using the proprietary Jet Electrochemical Silver Extraction (JESE) recovery method have successfully produced silver of exceptional purity within a very short processing time, reinforcing the potential of this technology to deliver significant commercial and environmental benefits. The JESE process yielded silver at a purity level of 95.95% (Ag %w/w) which is comparable to Britannia-grade silver, a high-quality alloy. The analysis shows that the total impurity content in the recovered silver is just 4.05%, markedly lower than the 21.37% impurity level measured in conventional E-bath recovery/deposition trials. The benchmarked E-bath recovery/deposition method produced only 78.63% silver content after the same five-minute trial, with significantly higher aluminium (11.40%) and oxygen (8.41%) contamination. These findings demonstrate that the JESE method can consistently deliver near-commercial grade silver in a single recovery step, minimizing the need for intensive secondary purification and supporting scalable industrial adoption. From a sustainability perspective, the low-impurity profile means less chemical consumption in downstream refining and reduced waste generation.

Building on these promising results, LU7 and the Macquarie University team will continue optimisation studies to refine operating parameters and further enhance silver purity. Larger-scale pilot tests are planned to validate the performance under continuous operating conditions and examine the recovery efficiency for other high-value metals, supporting the Company's broader goal of establishing a comprehensive recycling solution for the solar industry.
